Abstract and Keywords

This article focuses on templated carbon nanotubes (CNTs) and how their cavities can be used for the synthesis of nanomaterials. In particular, it demonstrates how effectively the CNTs can be functionalized by the template carbonization technique. The article first describes the method for synthesizing CNTs and carbon nano-test-tubes (CNTTs). It then considers the controlled filling of magnetic materials into CNTTs, taking into account the electrochemical deposition of Ni-Fe alloy and the magnetic properties of NiFe-filled CNTTs. It also examines the synthesis of water-dispersible and magnetically responsive CNTTs, with emphasis on water dispersibility and the effect of magnetic interaction. Finally, it shows how the cavities of templated CNTs can be utilized as a reaction field for the hydrothermal synthesis of one-dimensional nanomaterials.

Keywords: carbon nanotubes, cavities, nanomaterials, template carbonization technique, carbon nano-test-tubes, electrochemical deposition, magnetic properties, water dispersibility, reaction field, hydrothermal synthesis
